Abstract
A method for rendering a gallbladder dysfunctional without surgical removal comprises the steps of infusing the gallbladder with methyl-tert-butyl ether (MTBE), then, while the gallbladder is so infused, irradiating the gallbladder with an ultrasound beam in such an ultrasound delivery format as not to elevate the average temperature of the gallbladder more than five degrees Centigrade over the period of treatment, and then removing the MTBE from the gallbladder.
